市政道路路基冻胀和翻浆的影响因素及防治措施分析

Analysis of Factors Affecting Frost Heaving and Mudding of Municipal Roadbed and Its Prevention Measures

冻胀、翻浆是我国冻土区城市市政公路在使用过程中常出现的主要病害现象之一,当这种现象出现时,不仅导致市政公路路面逐渐出现裂缝、坍塌以及断裂等情况,而且也对过往车辆的交通安全产生极大威胁,对我国市政工程质量、城市发展建设进度以及我国公路工程行业发展造成严重影响,对我国经济和社会效益也均产生一定影响。基于此,文章对市政公路道路路基冻胀、翻浆现象出现的主要原理、导致因素等进行了简要阐述与分析,并结合实例对如何就路基冻胀和翻浆现象加以防治提出几点有效措施,以期进一步提升我国冻土区市政公路质量和交通水平。

Frost heaving and mudding are main phenomena that often occur in the urban municipal highways in China’s permafrost regions.When this phenomenon occurs,it not only causes cracks,collapses and breaks in the municipal road surface,but also brought great threats for the traffic safety of passing vehicles,affected the quality of municipal engineering projects,the development of the urban and the development of China’s highway engineering industry,and had a certain impact on China’s economic and social benefits.Based on this,this paper briefly expounded and analyzed the main principles and causes of the occurrence of frost heaving and mudding on the roadbed of municipal highways,and proposed some effective measures to prevent and control the roadbed frost heaving and mudding,with a view to further improve the quality and traffic level of municipal roads in China’s permafrost regions.
